"Castle" Season 7 filming is underway, and its premiere date on ABC has been set. Stana Katic, who plays Kate Beckett, updates her profile photo on Twitter to make sure that fans remember the last season's cliffhanger. Nathan Fillion is not dishing filming updates or BTS photos, but he still answers fans' questions once in a while. There are more teasers from show bosses and the rest of the cast; read on.

Stana Katic's Twitter update -- a behind the scenes photo featuring Castle 7x01 director Rob Bowman -- on Castle Season 7 filming has been well-received. It has drawn nearly 7,000 combined "retweets" and "favorites." Ms Katic's profile photo cannot be missed, too. It takes fans back to that moment in S6 when Kate Beckett, on the hour of her wedding to Rick, receives a devastating phone call.

To some fans, it physically hurts to wait for what happens in the Castle Season 7 premiere, even more so when they are constantly reminded of the wedding disaster with which S6 ended. To others, Katic's and Fillion's presence on Twitter helps them in coping with Caskett separation anxiety.

Meanwhile, new show boss David Amann and series creator Andrew W. Marlowe assured Caskett fans that the blazing car wreck in S6 would not end things between Castle (Fillion) and Beckett (Katic). The tragedy "will make them stronger" in Castle Season 7, Amann told TVLine.

Mr Marlowe, in the same interview, teases an interesting direction in Castle Season 7. Fans have often commented in social networks and forum sites how little has been revealed about Rick Castle. Beckett faced the very same issue earlier in the season. Next season, viewers get to know more about Rick.

"We're looking to open up some really interesting aspects of storytelling for the Castle character, who hasn't been as deeply explored as Beckett over the past six years - and we're really excited by that opportunity," Marlowe said.

Marlowe, despite stepping down as the Castle show boss, remains very much in the loop when it comes to series development. In fact, TVLine revealed Marlowe is writing Castle Season 7, Episode 2.

Molly Quinn, who plays Alexis Castle, has her own Castle Season 7 premiere episode teaser too:
